Question

Find the surface area

Answer 1

Answer = 221.52cm²

Explanation:

Surface area of a hexagonal pyramid = B × H ÷ 2

Where,

b = 6

h = 5.2

⇒ 6 × 5.2 ÷ 2 = 15.6

⇒ 15.6 × 5.2 = 81.12

⇒ 6 × 9 ÷ 2 ⇒ 54 ÷ 2 = 27

⇒ 27 × 5.2 = 140.4

140.4 + 81.12

= 221.52

Answer 2

Explanation:

a -> apotham of the hexagon ⇒ a = 3√3 cm

b -> base ⇒ b = 6 cm

s ->slant height ⇒ s= 9 cm

`\text{Area of hexagonal pyramid=3*ab +3*b*s}`

= 3*3√3*6 + 3*6*9

= 54*1.732 + 162 [√3 = 1.732]

= 93.6 + 162

= 255.6 cm²
